Title: Improvements in or relating to coin controlled mechanism
IPC: G07F5/20
Filed: 1937-07-20
Abstract: 498,145. Coin - controlled apparatus. BRECKNELL, MUNRO, & ROGERS (1928), Ltd., and DOLMAN, H. J. July 20, 1937, No. 20023. [Class 27] Coin action, mechanical-connection and multiple-coin.-Relates to coin-controlled mechanism of the kind described in Specification 320,613, [Class 27], in which coins inserted in a bunch in a shoot 6, Fig. 1, are fed forward by a powerdriven rotary disc 4 to actuate a control element 14 in accordance with the value of the particular coin and, when coins amounting to a predetermined value have passed, the control element 14 effects or permits operation of the mechanism controlled. According to the invention, in order that the mechanism may be operated by polygonal threepenny bits as well as by pennies and halfpennies, two feelers are provided operating the control element 14, one being actuated by the pennies and halfpennies and the other by the threepenny bits. The disc 4 rotates in a casing 1 which is inclined at 60 degrees to the horizontal and is covered at its lower portion by a plate 5 carrying the shoot 6. The outer portion of the disc 4 is cut away to form an annular recessed path 15 divided into coin pockets 16 by pins 17 and arcuate ramps 18. The recess 15 is also provided on the same circle as the pins 17 and ramps 18 near the trailing ends of the pockets 16 with conical holes 20 flaring downwardly. The coins carried round in the pockets are discharged through an opening 45 formed by a recessed passage 21 in a plate 7. The recess 21 is formed with a passage 25, Fig. 3, just wide enough to take the threepenny bits, this passage being deeper at its upper than at its lower edge 48. A curved recess 22 allows the ramps 18 to pass. As the coins are carried round by the disc 4, the pennies and halfpennies actuate a feeler or finger 43 and rotate the toothed ratchet wheel 14 through two teeth for a penny and one tooth for a halfpenny. Threepenny bits are too small to actuate feeler 43, but are carried round and enter the passage 25. The nose 35 of a spring-pressed lever 10 enters a hole 20 and tilts the threepenny bit about the edge 48 so that it presses on a pin 31 on the lower of a pair of spring contact strips forming an electric switch 28. The circuit of a solenoid 32 is thereby closed and a rod 34 extending from its core 33 actuates an arm 41 bearing a pawl 42 which moves the wheel 14 through six teeth. Pennies and halfpennies are too large to enter the passage 25 and are discharged through the opening 45. The wheel 14 is provided with contacts 38 which successively engage momentarily with a brush 39 and close an electric circuit each time the wheel is moved through a predetermined distance, said circuit acting to effect or permit the actuation of the mechanism controlled.

Title: Digital to phase analog converter
IPC: H03M1/00
Filed: 1965-05-14
Abstract: 1,088,151. Digital-to-analogue converters. INTERNATIONAL STANDARD ELECTRIC CORPORATION. May 14, 1965 [May 18, 1964], No. 20426/65. Heading G4H. In a digital to phase analogue converter, digital input signals are compared with clock signals at a first frequency to produce phase information signals at a second frequency, and reference signals at the second frequency are derived from the clock signals, the phase difference between the reference signals and the phase information signals being proportional to the digital input signals. The clock pulses are fed to a binary counter the contents of which are compared with the digital (binary) input signals to set a flip-flop when they agree and reset the flip-flop again when they next disagree in the most significant bit only. The flip-flop provides the phase output signal, and the reference signal mentioned is derived by inverting the most significant bit from the counter. The two signals may position a shaft using a servo system.

Abstract: 697.268. Washing granular materials. FAIRWEATHER, H G. C. (RAKOWSKY, V.). Aug. 31, 1951, No 20555/51. Class 82(ii) A sink and float process of separating material into light' and heavy fractions comprises feeding the material into a bath of self-sustaining separating medium whereby a supernatant zone of low medium content is formed, overflowing the supernatant zone, overflowing medium and floats immediately below t h e supernatant zone, draining the products from both these overflows and recirculating at least a portion of the drainage from the product containing the float material, washing adherent medium from the float material, cleaning at least some of the washings and returning the cleaned medium at a predetermined density to the separating medium, thickening the drainage from the supernatant zone and returning this thickened product to the separating zone. In the process shown in the flow sheet, Fig. 1, the separatory vessel receives the feed and make-up medium and the sink and float products are removed and screened, the drainage then being returned to the vessel. The sink and float products are then washed and the washing, with the optional addition of some of the sink and float drainings, are passed, via a magnetizing element if the medium'is magnetic, to a thickener. The thickened medium is then cleaned, dewatered, demagnetized and returned as make-up medium. The supernatant zone, removed from the separatory vessel, is screened and the drainings are either (a) combined with the sink and float washings for thickening therewith, or (b) passed to a separate thickener and returned as part of the make-up medium. The density of the make-up medium may be controlled by automatically varying the amount of return water supplied. In theform of separatory vessel shown in Fig. 3, the float material flows over a lower weir 4 while the supernatant water layer which is built up by a curved baffle 11 is skimmed off together with some light waste 14 by an adjustable weir 8.
